What is the first step in creating an Organizational Unit (OU)?

Opening "Active Directory Users and Computers" is the first step in creating an Organizational Unit (OU) because this tool provides the graphical interface necessary to manage Active Directory resources. Through this utility, an administrator can navigate the directory structure, view existing OUs and user accounts, and utilize the right-click menus to start the process of creating a new OU. This step is fundamental because the Active Directory Users and Computers interface is specifically designed for user and organizational management tasks, making it an essential part of the workflow.

While logging into the server, accessing the command line, or contacting the administrator for permissions may be relevant activities in the context of overall user account management, they are not the initial actions specifically required to create an OU. Logging in is a prerequisite to accessing any tools, but the direct action of starting the OU creation process begins with navigating to the Active Directory management interface.
